7 ATTACHMENT FOR SOUND REPRODUCING MACHINES Filed Feb. 26, 1929INVEQJTOR fzvl ge Lazag A'I'TO EY Patented Mar. 17, 1931 GEORGE LAING,OFiGALGARY, ALBERTA, CAN ADA .A'ITACHIi/IEN'I. FOR SOUND-REPRODUCINGMACHINES Application filed. February 28, 1829, Serial No. 342,860, andin Canada July 20, 1928.

.provide the attachment with an adjustable or movable screen arranged asa closure for said discharge opening but of such a nature as to notmaterially interfere with the transmission of sound therethrough; afurther object being to provide means for eliminating the stagerepresentation or chamber of the attachment in pleasing color effects;and with these and other objects in view, the invention consists in aoevice of the class and for the purpose specified which is simple inconstruc tion, eiiicient in use and which is constructed e ashereinafter described and claimed.

The invention is fully disclosed in the following specification, ofwhich the accompanying drawing forms a part, in which the separate partsof my improvement are designated by suitable reference characters ineach of the views, and in which Fig. 1 is a front elevation of theattachment, part of the construction being broken away and in section.

Fig. 2 is a sectional, plan view taken on the line -00 of Fig. 1.

Fig. 3 is a sectional side elevation; and,

Fig. 4 is a side elevation showing part of a gramophone or otherapparatus in section.

In the accompanying drawings, 1 represents the attachment proper whichas will be seen, adapted to be supported in connection with a gramophone2 or the cabinet or casing of other reproducing or transmittingapparatus of any kind or class. At 3 and 4:, I have shown two doorshinged to the casing 2 at opposite sides of an opening 2a formedtherein, through which opening, the sound or is in the form of aminiature stage,

tone transmitted from the apparatus is adapted to pass.

Hook-shaped supportingbrackets 5 and 6 are adjustably supported .inconnection with the side walls 7 and 8 of the attachment .1, and saidwalls are preferably inclined backwardly to form a'n-Jarrow'er rear endportion as clearly :seen in Fi 2 of the drawing. The brackets areadapted .to hang over the top edges '9 and 10 of the doors as clearlyseen 1Il.FlgS. 1,2 and t ofthedrawing. Ar ranged at the back of theattachment is a screen 12 which is .mou-nted upon rollers 1-3 and 1&located in the upper :and lower portions of theattachment, said screenbeing capable of upward and downward movement by the rotation of knobs15 and :16 provided at one end otcach roller.

VVit-hthis construction, atpleasing, appropriate or harmonizingsceneprintechpa-inted or otherwise applied to the screen may be broughttoview withinthe cabinet or at the rear portion of the stagerepresentation formedthereby. This scene maybe varied from time to timetobe consistent withthe music or other selection played by the apparatusin connection with which the attachmentis employed.

I also preferably arrange fat the top 17 of the attachment, a pluralityof electricbu'lbs preferably of diiterentjcolorsin orderto providedifierent color efiectathe electrica'lconnections and control beingcared for along conventional lines. A plurality of small holes 18 arealso preferably formed in the frieze of "the 'entablature at the frontofthe attachment-to allow the'heat from the bulbs to pass'through the sameand at the same time to form small lights in frontof the stage.

I Portable figures or scene pieces such as indicatedat '19 may beused'upon the stageto increase the attractiveness of the stage'setting,and again, these figures arepreferably consistent with the selection orreproduction which is transmitted tromfth'e apparatus'in connection withwhich the attachment is employed.

It willbeunderstood that my inven'tion is not necessarily limited to thespecifiqstr-ucof the doors,

tural details herein shown and described, nor to the manner ofsupporting or arranging the attachment, and various other changes in andmodifications of the construction herein shown and described may be madewithin the scope of the appended cliams, without departing from thespirit of my invention or sacrificing its advantages.

Having fully described my invention, what I claim as new and desire tosecure by Letters Patent, is i 1. An attachment in combination withgramaphones and other musical devices, constructed to rest and liebetween the doors of the same when open, the attachment having hooks orsupports to fit and take the top edge a screen having scenes thereon,said screen being carried by rollers, the screen being capable ofmovement to change the scenes, substantially as set forth.

2. An attachment in combination with gramaphones and other musicaldevices constructed to rest and lie between the doors of the same whenopen, the attachment having Q, hooks or supports to fit and take the topedges of the doors, a screen having scenes thereon, said screen beingcarried by rollers, the screen being capable of movement to change thescenes as desired, lighting arrangement for different colored lights,holes in the front of the attachment, all substantially for the purposeas set forth.

3. An attachment formed as a stage in combination with gramaphones andother musical devices constructed to rest and lie between the doors ofthe same, hooks or supports to fit and take the top edge of the doors, ascreen having scenes thereon, said screen being carried by rollers, thescreen being capable of movement to change the scenes, lightingarrangement for diflerent colored lights, all as a stage setting for thepurpose of conveying to an audience the atmosphere of the theatresubstantially as described and set forth.

4. An attachment formed as a stage setting, means for detachablysupporting said attachment in connection with a sound reproducingapparatus to arrange the same in the path of the transmission of soundfrom said apparatus, and said attachment including a shiftable sceneelement disposed in the path of said sound and through which the soundis free to pass.

5. An attachment formed as a stage setting, means for detachablysupporting said attachment in connection with a sound reproducingapparatus to arrange the same in the path of the transmission of soundfrom said apparatus, said attachment including a shiftable scene elementdisposed in the path of said sound and through whichthe sound is free topass, said attachment comprising a casing, the front and back walls ofwhich are open, the front wall being characterized to represent a stage,and means for illuminating the interior of said casing.

6. An attachment formed as a stage setting, means for detachablysupporting said attachment in connection with a sound reproducingapparatus to arrange the same in the path of the transmission of soundfrom said apparatus, said attachment including a shiftable scene elementdisposed in the path of said sound and through which the sound is freeto pass, said attachment comprising a casing, the front and back wallsof which are open, the front wall being characterized to repre sent astage, and means for illuminating the interior of said casing and sceneelements supported within said casing.

In testimony that I claim the foregoing as my invention I have signed myname this 19th day of February, 1929.

GEORGE LAING.
